After Guo Bin and his entourage arrived, Zhang Shiping and Su Shuang greeted them directly to the central building of the city, the Yamen, which is an important building that will inevitably exist in every city.

However, because these three cities are strictly Guo Bin's private estates, not built by the Han Dynasty in the serious sense of the 800 Han Dynasty, their urban layout and architectural design are completely planned by Guo Bin, and their specific construction is also completed by Yang Zhai Construction Co., Ltd.

The role of this yamen is roughly the same as that of the common county government in the Central Plains, and it is the administrative center of the whole city. It has the functions of hearing cases, checking household registration, and collecting taxes, and also has functional buildings including arsenals, grain depots, and document warehouses. In addition, this yamen has more administrative service functions than ordinary county yamen.

Because the three cities outside the Seychelles are, to put it bluntly, a city with economy and trade as the core, consisting of a main city and two satellite cities. In the main city where Guo Bin is currently located, there are all kinds of buildings such as taverns, tea houses, inns, etc., if you don't look at the clothing of pedestrians, it is not an exaggeration to say that it is a big city in the Central Plains.

In this central city, in addition to the Yamen, the most core functional building is probably the trading house built opposite the Yamen.

In this trading house, most of the products that can be sold in the city are gathered, and each product has a corresponding showcase. Of course, if you want to have your own showcase here, you have to pay a lot of rent. Correspondingly, there are the most basic and basic storage warehouses in the city.

The showcases in the trading house are like the storefronts of the shops, and they are filled with goods that are used as samples. Among these goods are finished products or raw materials such as felt, wool, cheese, and butter produced on the grasslands, as well as luxury goods such as tea, clothing, and fine wine transported from the Central Plains. Even the silk silk of Linzi, the splendid embroidery of Shudi, and the Wenbei of Guanghan, which can be called high-end luxury products in the Central Plains, can be bought here.

In addition, the highly prestigious Yangzhai clothing in the Central Plains also has its own showcase here. The raw material required for the production of wool is wool, and because of its proximity to the raw material production area of wool and the abundant Han labor force, Yang Zhai clothing seized the opportunity to build a workshop for woolen production and garment production in the city.

They adopted the method of garment production in later generations, and divided the garments into several sizes according to the body shape of the people at this time, and marked them with seven sizes: "small three, small two, small one, standard, big one, big two, big three", so that the production of ready-to-wear can be scaled. In this way, the production efficiency has been greatly improved, thereby reducing the production cost, in Guo Bin's view, there is finally a preliminary prototype of the garment factory in later generations.

Don't underestimate this little change, which can be injected into Guo Bin's hard work. The result, which ultimately satisfied Guo Bin, was the "standardized production" that was most often mentioned in the early days of later industrialization. Standardized production makes the cutting of clothes faster, and with the assembly line production mode, it can make the production of ready-to-wear garments take into account both efficiency and quality.

In the era of handicraft production in the past, the production and production of a piece of clothing was often done by one person from beginning to end. From measuring to cutting fabrics and sewing clothes, it is often done by a single tailor. Of course, this is only for the landlords at this time, those ordinary people, can get rid of the fate of being unclothed has to thank God, where will there be any requirements for its style?

However, this kind of production mode in which one person covers all the processes of garment production, its low production speed and the instability of product quality are doomed to the backwardness of this production model. This mode of production makes it difficult to form large-scale and industrialized production.

Guo Bin's knowledge from later generations, which can even be said to be common sense, played a great role at this time. He first asked the master recruited by Yang Zhai Clothing to cut out a piece of clothing of a standard body shape, and then ordered someone to trace the "parts" of these clothes according to their shape and size. Thus, the standard of cutting was determined.

In later generations, the cutting of clothing was made by computers, but now there is no such condition, so Guo Bin asked people to directly make a lathe for cutting according to the standard of clothing, and cut the whole fabric out with a cutting knife made according to the standard. All that's left is how the "parts" are stitched together and the details (e.g. buttonholes on clothes, button fitting, etc.).

It is worth mentioning that because the style of ready-to-wear at this time is somewhat single, only the standard military uniforms of Yangzhai County are sold in Yangzhai clothing, so this slightly clumsy production method can still meet the demand.

In addition, regarding the sewing of clothes, Guo Bin put forward the "concept" of a sewing machine. Although he doesn't know how the sewing machine works, Guo Bin has at least seen the sewing machine, and he also knows the huge role of the sewing machine! Therefore, he handed over this idea to Sima Hui and asked him to set up a new mechanical research laboratory in Yangzhai County School, bringing together students and teachers who are very interested in new mechanical research.

This kind of so-called strange skills that are close to the Mohists are not recognized by the mainstream society, so the laboratory established in Yangzhai County School is only a relatively loose temporary organization gathered on the basis of hobbies.

In fact, the principle of the sewing machine is not too difficult, it just requires an idea, plus a less complicated loop stitching system to complete. Guo Bin had the idea, and even the shape he figured out with comparison, and the rest was how to complete the design of this coil suture system.

Otherwise, knowledge is productivity, this coil stitching system was finally realized in the hands of Ma Jun, who was addicted to the three laws of mechanics proposed by Guo Bin, and he even made a "primitive" foot-operated sewing machine through several linkage shafts.

Although this design is still a little crude, no one knows the significance of this design better than Guo Bin: it will greatly improve the speed of garment production, and at the same time, it will also change the production mode of garment production. This extremely high production efficiency, on the basis of greatly reducing production costs, will help Yang Zhai clothing to achieve the strategic goal of clothing in the world.

Therefore, Guo Bin personally ordered the establishment of the Fulong Villa Sewing Machine Manufacturing Factory, led by Fulong Villa, specializing in the production of sewing machines with core technology mastered by Ma Jun, and let Ma Jun take the technology as a shareholder and serve as the technical consultant of the manufacturing plant. Due to the great success of the sewing machine, Ma Jun has obtained extremely rich economic benefits, and his status in Fulong Villa and even the entire Yangzhai County has naturally risen.

The power of role models is endless, and Ma Jun's success has led to a quiet upsurge of invention and creation in Yangzhai County. Seeing that people no longer scoff at the so-called tricks and tricks, Guo Bin also had to sigh: "The process of changing customs is sometimes very fast, and it does not require strong government intervention. ”

At the same time, the three laws of mechanics, which were proposed by Guo Bin and gradually enriched and perfected with the efforts of Sima Hui, Ma Jun and others, became very popular in Yangzhai County and became a sought-after scholar for a while.

However, the road to industrialization is long. Stimulated by the standardization of the garment manufacturing industry and the assembly line production model, Guo Bin realized an extremely important thing, that is, the standardization of weights and measures.

An important achievement of standardized production is the realization of generalization. The so-called generalization refers to the selection and determination of a standardized form of subsystems or functional units with functional interchangeability or size interchangeability in an independent system. In other words, the same parts in two machines with the same specifications can be used interchangeably.

This is the premise of generalization: interchangeability. That is, the performance that products or parts manufactured at different times and places can be replaced at will without modification during assembly and maintenance.

Don't underestimate this feature, let's take a simple example: horse-drawn carriages.

Before the Qin Dynasty, the size of the carriages in various countries during the Spring and Autumn Period and the Warring States Period was different, and even the size of the same carriage made by the same person was also different. At this time, when people make objects, they largely consider their practicality, as long as the carriage can run and can be kept for many years, it is a good carriage. Who cares how many spokes this carriage has, or how big the wheels are? If you can use it, you can use it!

However, after the establishment of the Qin Dynasty, it was stipulated that the carriage should be on the same track, that is, the distance between the two wheels of the carriage should be the same. This standardization made it possible for the wheels of the two carriages to be interchangeable.

In the past, if the axle of a car was broken, it was necessary to find a similar material and rework it before it could be used again. Now, you can remove the axle of a carriage with a broken wheel and an intact axle and use it on this carriage without the need for extra machining steps.

This great convenience will play a great role when applied on the battlefield.

When cleaning up the battlefield, recycling used feather arrows is also a must-do. In particular, the feather arrows of the Han Dynasty were made of iron melting, and their penetration and stability were extremely high. The arrow feathers are made of specific bird feathers, a small feather arrow, but the process is extremely complicated.

And the recovered feather arrows will inevitably have problems of one kind or another. Some of the shafts are broken, and some of the feathers are falling off, and then the interchange of parts is highlighted. The reassembled feather arrow not only ensures its lethality and quality, but also greatly saves costs. And this method, at the same time, also greatly reduced the cost of transportation of military materials, laying a solid foundation for victory in the war. Needless to say, the huge impact that the cost of material transportation played in the war is needless to say.

In order to achieve this standardization, Guo Bin has also made great efforts.

Although Qin Shi Huang fully demonstrated his majesty and strategy at the beginning of the establishment of the Qin Dynasty and unified weights and measures, its minimum unit of measurement also made the measurement error at this time very large.

In the Han Dynasty, the unit of measurement was divided into "minutes, inches, rulers, zhang, and citations", and the "Hanshu Laws" recorded: "The degree is also the degree of the ruler, so the length of the degree is also... Ten inches, ten feet for zhang, ten zhang for the lead". According to expert research, one ruler in the Han Dynasty was equal to 231-235 mm, and one inch was about 23 mm based on 230 mm. Therefore, the smallest unit of measurement at this time was 2.3 millimeters, which was a full three times more than the millimeter in later generations.

As a result, the error is also one or three times greater when the measurement is made.
